Description

Die Erfindung bezieht sich auf eine Vorrichtung gemäss dem Oberbegriff des Anspruchs 1.The invention relates to a device according to the preamble of claim 1.

Bei der operativen Frakturversorgung im maxillofacialen Bereich, sowie im Hand- und Fuss-Bereich, kann eindeutig die Tendenz festgestellt werden, dass immer kleinere Implantate bevorzugt werden. Der Grund dafür ist das allgemein grösser werdende Verständnis über die biomechanischen Grundlagen der Osteosynthese. Im Bereich der maxillofacialen Frakturbehandlung kann Dank der Miniaturisierung Von Implantaten mehr Rücksicht auf das kosmetische Resultat einer Osteosynthese genommen werden.With surgical fracture care in the maxillofacial area, as well as in the hand and foot area, the tendency can be clearly established that smaller and smaller implants are preferred. The reason for this is the generally growing understanding of the biomechanical foundations of osteosynthesis. In the field of maxillofacial fracture treatment, thanks to the miniaturization of implants, more consideration can be given to the cosmetic result of an osteosynthesis.

Im Bereich der Handchirurgie können Bewegungseinschränkungen im Fingerbereich vermieden werden. Osteosynthese-Implantate im Fingerbereich kommen unter die Sehnen zu liegen. Bei einem Implantat mit grossem Querschnitt, kann die Sehne nicht mehr maximal gedehnt werden.In the field of hand surgery, movement restrictions in the finger area can be avoided. Osteosynthesis implants in the finger area come under the tendons. With an implant with a large cross-section, the tendon can no longer be stretched to the maximum.

Die Dimensionen der sogenannten Mini-Implantate (Schrauben und Platten) liegen im Bereich von 0,8 mm - 2,0 mm. Durch diese Miniaturisierung sind Probleme im Bereich der Verpackung, Lagerung, sowie in der Handhabung beim Operationsvorgang entstanden. Die Handhabung im Operationssaal hat sich besonders im maxillofacialen Bereich, als schwierig erwiesen. Je nach Schwierigkeitsgrad der Fraktur oder Korrektur, werden bis zu 40 Knochenschrauben eingebracht. Diese Schrauben müssen einzeln von der OP-Schwester einem sogenannten Schraubenrechen entnommen, auf ihre Länge geprüft, auf einen Schraubenzieher gesetzt und dem Chirurgen übergeben werden. Dieser wiederum muss sie, durch die Osteosyntheseplatte, in das vorgebohrte Schraubenloch setzen. Bei der Schraubenübergahe und beim Versuch die Schraube einzudrehen, fällt diese oft vom Schraubenzieher, in die Wunde oder in die OP-Abdeckung. Der Versuch eine verlorene Schraube zu finden ist, bei deren Abmessungen (Durchmesser 0,8 mm x 4,0 mm), zu zeitaufwendig und würde die OP-Zeit verlängern. Da der Verlust von Schrauben durch die Handhabung im OP, bei der Verpackung und bei der Sterilisation recht häufig ist, entstehen dem Spital unnütze Kosten.The dimensions of the so-called mini implants (screws and plates) are in the range of 0.8 mm - 2.0 mm. This miniaturization has caused problems in the area of packaging, storage and handling during the surgical procedure. The handling in the operating room has become special in the maxillofacial area, proven to be difficult. Depending on the degree of difficulty of the fracture or correction, up to 40 bone screws are inserted. These screws have to be taken individually by the surgical nurse from a so-called screw rake, checked for their length, placed on a screwdriver and handed over to the surgeon. The latter, in turn, has to insert it through the osteosynthesis plate into the predrilled screw hole. During the screw transition and when trying to screw in the screw, it often falls from the screwdriver, into the wound or into the surgical cover. Trying to find a lost screw, with its dimensions (diameter 0.8 mm x 4.0 mm), is too time-consuming and would increase the operating time. Since the loss of screws due to handling in the operating room, packaging and sterilization is quite common, the hospital incurs unnecessary costs.

Ein weiteres Problem im Umgang mit Minischrauben wird nachfolgend beschrieben. Nachdem der Chirurg, die für die jeweilige Fraktur geeignete Osteosyntheseplatte ausgewählt hat, positioniert er die Platte über dem Frakturspalt. Danach bohrt er durch eines der Plattenlöcher die Kernbohrung für die Schraube (Durchmesser 0,5 - 1,5 mm). Nach dem Bohrvorgang übernimmt er von der OP-Schwester die benötigte Schraube und dreht diese durch die Platte in den Knochen. Das Problem dabei ist oft das Auffinden der Kernlochbohrung im Knochen, da die Knochenoberfläche mit Blut oder mit Weichteilen bedeckt ist und die Platte auf der glatten Knochenoberfläche rutschen kann.Another problem with handling mini screws is described below. After the surgeon has selected the appropriate osteosynthesis plate for the respective fracture, he positions the plate over the fracture gap. Then he drills the core hole for the screw (diameter 0.5 - 1.5 mm) through one of the plate holes. After the drilling process, he takes over the necessary screw from the surgical nurse and turns it through the plate into the bone. The problem is often finding the core hole in the bone, since the surface of the bone is covered with blood or soft tissue and the plate can slide on the smooth surface of the bone.

Hier will die Erfindung Abhilfe schaffen. Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zur kontinuierlichen Darreichung und Applikation von osteosynthetischen Fixationselementen, insbesondere von Knochenschrauben zu schaffen. Eine weitere Aufgabe besteht darin eine Verpackung für solche osteosynthetische Fixationselemente zu schaffen, welche gleichzeitig zur Aufbewahrung im Operationssaal und als Dispensor für den Chirurgen dient.The invention seeks to remedy this. The invention has for its object to provide a device for the continuous presentation and application of osteosynthetic fixation elements, in particular bone screws. Another object is to provide packaging for such osteosynthetic fixation elements, which is used simultaneously for storage in the operating room and as a dispenser for the surgeon.

Die Erfindung löst die gestellte Aufgabe mit einer Vorrichtung, welche die Merkmale des Anspruchs 1 aufweist, sowie einer Drehtrommel für diese Vorrichtung, welche die Merkmale des Anspruchs 9 aufweist.The invention achieves the stated object with a device which has the features of claim 1 and a rotary drum for this device which has the features of claim 9.

Die durch die Erfindung erreichten Vorteile sind im wesentlichen darin zu sehen, dass dank der erfindungsgemässen Vorrichtung ein effizientes Werkzeug für den Chirurgen geschaffen wird, mit dem die Vorratshaltung für osteosynthetische Fixationselemente, insbesondere für Knochenschrauben, die intraoperative Darreichung und Applikation solcher Fixationselemente extrem erleichtert wird. Die erfindungsgemässe Vorrichtung dient neben der Darreichung der Fixationselemente gleichzeitig auch als Bohrlehre und Führung für den Schraubenzieher, mit dem die Fixationselemente, insbesondere Knochenschrauben eingedreht werden.The advantages achieved by the invention are essentially to be seen in the fact that, thanks to the device according to the invention, an efficient tool is created for the surgeon, with which the stockpiling for osteosynthetic fixation elements, in particular for bone screws, the intraoperative administration and application of such fixation elements is extremely facilitated. In addition to the presentation of the fixation elements, the device according to the invention also serves as a drilling jig and guide for the screwdriver with which the fixation elements, in particular bone screws, are screwed in.

Die in den Fig. 1 - 5 dargestellte Vorrichtung gleicht in ihrem Aufbau einem Trommelrevolver. Die Trommeleinrichtung 3 besteht aus einem, eine Drehnabe 5 aufweisenden Trommelgehäuse 6,7 zur Aufnahme einer um die Achse 2 der Drehnabe 5 rotierbaren Drehtrommel 10, mit mehreren, peripher angeordneten und parallel zur Achse 2 verlaufenden, als Vorratskammern für Knochenschrauben 1 dienende durchgängige Bohrungen 4.
Das Trommelgehäuse 6,7 besteht seinerseits aus zwei durch die Drehnabe 5 verbundenen Tellern 6 und 7, wobei das Trommelgehäuse 6,7, beziehungswwiese die Teller 6 und 7, nicht auf der Drehnabe 5 rotiert werden können.
Der obere, fest mit einem Handgriff 9 verbundene Teller 6 ist mit einer Zugangsöffnung 14 zur Einführung eines in den Fig. 6 und 7 dargestellten Instrumentes 21 und 22 versehen, wobei das Zentrum der Zugangsöffnung 14 den gleichen Abstand zur Achse 2 aufweist wie die Zentren der peripher angeordneten und parallel zur Achse 2 verlaufenden, als Vorratskammern für die Knochenschrauben 1 dienenden durchgängigen Bohrungen 4.
Der untere, fest mit der Drehnabe 5 verbundenen Teller 7 ist mit einer Austrittsöffnung 13 für die Knochenschrauben 1 versehen, wobei das Zentrum der Austrittsöffnung 13 den gleichen Abstand zur Achse 2 aufweist wie die Zentren der Bohrungen 4.An embodiment of the invention, which also explains the principle of operation, is shown in the drawing and will be described in more detail below.

The device shown in FIGS. 1-5 is similar in structure to a drum turret. The drum device 3 consists of a drum housing 6, 7 having a rotating hub 5 for receiving a rotary drum 10 which can be rotated about the axis 2 of the rotary hub 5, with a plurality of through bores 4 which are arranged peripherally and run parallel to the axis 2 and serve as storage chambers for bone screws 1.
The drum housing 6,7 in turn consists of two plates 6 and 7 connected by the rotating hub 5, the drum housing 6,7 or the plates 6 and 7 not being able to be rotated on the rotating hub 5.
The upper plate 6, which is firmly connected to a handle 9, is provided with an access opening 14 for introducing an instrument 21 and 22 shown in FIGS. 6 and 7, the center of the access opening 14 being at the same distance from the axis 2 as the centers of FIG peripherally arranged through holes 4 running parallel to axis 2 and serving as storage chambers for bone screws 1.
The lower plate 7, which is firmly connected to the rotary hub 5, is provided with an outlet opening 13 for the bone screws 1, the center of the outlet opening 13 being at the same distance from the axis 2 as the centers of the bores 4.

Der untere Teller 7 des Trommelgehäuses 6,7 besitzt ferner eine Gewebeschutzhülse 11, durch welche die Kernlochbohrung und das Setzen der Knochenschrauben 1 vorgenommen werden kann. Der Abstand der Achse 12 der Gewebeschutzhülse 11 zur Achse 2, entspricht dem Abstand der Schrauben- und Bohrlöcher 4, 18 in der Drehtrommel 10 zu ihrer Zentrumsachse 2. Der obere Teller 6 besitzt neben dem Handgriff 9 eine Bohrbüchse 15, die mit den Bohrungen 4 und 18 und der Achse 12 der Gewebeschutzhülse 11 übereinstimmt. Zudem besitzt der obere Teller einen gefederten Bolzen oder Kugel, die in die Indexierungen 17 der Drehtrommel 10 eingreifen kann. Dadurch können die Bohrungen 4 und 18 der Drehtrommel 10 mit der Gewebeschutzhülse 11 und der Bohrbüchse 15 einfach ausgerichtet werden.The lower plate 7 of the drum housing 6.7 also has a protective sleeve 11 through which the core hole and the setting of the bone screws 1 can be carried out. The distance between the axis 12 of the tissue protection sleeve 11 and the axis 2 corresponds to the distance between the screw and drill holes 4, 18 in the rotary drum 10 and its center axis 2. The upper plate 6 has, in addition to the handle 9, a drill sleeve 15 which is in contact with the holes 4 and 18 and the axis 12 of the tissue protection sleeve 11 coincide. In addition, the upper plate has a sprung Bolt or ball that can engage in the indexings 17 of the rotary drum 10. As a result, the bores 4 and 18 of the rotary drum 10 can be easily aligned with the tissue protection sleeve 11 and the drill sleeve 15.

Zur Montage der erfindungsgemässen Vorrichtung wird die fest mit dem unteren Teller 7 verbundene Drehnabe 5 durch die Hohlnabe der Drehtrommel 10 und eine (zeichnerisch nicht dargestellte) Öffnung im oberen Teller 6 hindurchgeführt und mit der Mutter 8 in einem bestimmten, die Rotierbarkeit der zwischen den beiden Tellern 6,7 drehbar gelagerten Drehtrommel 10 gewährleistenden, Abstand fixiert.To assemble the device according to the invention, the rotary hub 5, which is firmly connected to the lower plate 7, is passed through the hollow hub of the rotary drum 10 and an opening (not shown in the drawing) in the upper plate 6 and with the nut 8 in a certain manner, the rotatability of the between the two Plates 6,7 rotatably mounted rotary drum 10 ensuring distance fixed.

Die eigentliche Verpackung der Knochenschrauben 1, oder schraubenähnlichen Fixationselemente, ist somit die Drehtrommel 10 selbst, welche zirkulär angeordnete Bohrungen 4 und 18 besitzt. Dabei gibt es zwei verschiedene Bohrdurchmesser die sich untereinander abwechseln. Die grösseren Bohrungen 4 dienen zur Aufnahme der Knochenschrauben 1, die kleineren Bohrungen 18 zur Führung des Bohrers 21, für die Kernlochbohrung im Knochen, sowie des Schraubenziehers 22 zur Befestigung der Knochenschraube 1 im Knochen. Eine kreisförmig angebrachte Indexierung 17 auf der Trommeloberseite 19, erlaubt eine genau definierte Positionierung der gewünschten Bohrung 4 oder 18 innerhalb des Trommelgehäuses 6,7.The actual packaging of the bone screws 1, or screw-like fixation elements, is thus the rotary drum 10 itself, which has circularly arranged bores 4 and 18. There are two different drilling diameters that alternate with each other. The larger bores 4 serve for receiving the bone screws 1, the smaller bores 18 for guiding the drill 21, for the core hole drilling in the bone, and the screwdriver 22 for fastening the bone screw 1 in the bone. A circular indexing 17 on the drum top 19 allows a precisely defined positioning of the desired bore 4 or 18 within the drum housing 6,7.

Die Drehtrommel 10 ist einfach auswechselbar und dient gleichzeitig als Verpackung für die Knochenschrauben 1. Je nach Bedarf kann die Drehtrommel in einer sterilen Verpackung angeboten werden, oder sie kann erst im Spital sterilisiert werden. Statt die Drehtrommel 10 nach ihrer Erschöpfung mit einer neuen vollen Drehtrommel 10 auszutauschen kann sie auch über eine zusätzliche, im oberen Teller 6 angebrachte Einfüllbohrung 20 mit Knochenschrauben 1 nachgefüllt werden. Das Zentrum der Einfüllbohrung 20 muss konstruktionsbedingt den gleichen Abstand zur Achse 2 aufweisen wie die Zentren der Bohrungen 4.The rotary drum 10 is easily exchangeable and also serves as packaging for the bone screws 1. Depending on requirements, the rotary drum can be in a sterile packaging offered, or it can only be sterilized in the hospital. Instead of replacing the rotary drum 10 after its exhaustion with a new full rotary drum 10, it can also be refilled with bone screws 1 via an additional filling hole 20 provided in the upper plate 6. The center of the filling hole 20 must be at the same distance from the axis 2 as the centers of the holes 4 due to the design.

Im folgenden wird die intraoperative Handhabung der erfindungsgemässen Vorrichtung beschrieben:
Die mit Knochenschrauben 1 gefüllte Drehtrommel 10 wird in das Trommelgehäuse 6,7 geschoben, ohne die einzelnen Knochenschrauben 1 handhaben zu müssen. Der Chirurg benutzt nun die erfindungsgemässe Vorrichtung vorerst als Bohrbüchse, um die Kernlochbohrung für die zu setzende Knochenschrauben 1 in den Knochen zu bohren. Dabei wird der Bohrer 21 durch die Bohrbüchse 15 des oberen Tellers 6, durch eine der kleineren Bohrungen 18 der Drehtrommel 10 und durch die Gewebeschutzhülse 11 exakt geführt. Die Länge der einzelnen Führungselemente 15,11 sind mit der Länge der Bohrung abgestimmt. Dadurch kann die Bohrtiefe im Knochen, auf die Schraubenlänge angepasst werden. Die Spitze der Gewebeschutzhülse 11 ist auf die Schraubenlöcher in der Knochenplatte angepasst, wodurch die Knochenplatte auf den Knochen gedrückt wird und dadurch nicht mehr abrutschen kann. Der Chirurg führt nun die Kernlochbohrung im Knochen durch. Nach Entfernung des Bohrers 21, dreht der Chirurg die Drehtrommel 10 mittels ihrer peripheren Randrierung um eine Indexposition 17 weiter. Dadurch gelangt eine der, sich in der Drehtrommel 10 befindlichen Knochenschrauben 10, in den durch die Elemente 13 und 11 gebildeten Arbeitskanal. Je nach Beschaffenheit der Bohrung 4 in der sich die Knochenschraube 1 befindet, fällt die Knochenschraube 1 durch die Gewebeschutzhülse 11 auf die Knochenoberfläche, oder sie muss mit einem Schraubenzieher 22, durch die Gewebeschutzhülse 11 auf die Knochenoberfläche geschoben werden. Der Durchmesser des Schraubenziehers 22 ist auf den Kopfdurchmesser der Knochenschraube 1 angepasst, so dass er auf seiner ganzen Länge geführt ist und gezwungenermassen in den Antrieb der Knochenschraube 1 eingreift (Kreuzschlitz, Inbus usw.). Da die erfindungsgemässe Vorrichtung während des ganzen Arbeitsvorganges nicht entfernt werden muss, kann die Knochenschraube 1, ohne Aufsuchen der Pilotbohrung im Knochen eingedreht werden.
Nachdem die Knochenschraube 1 vollständig eingedreht ist, wird der Schraubenzieher 22 entfernt und die Drehtrommel 10 um eine Indexposition 17 weiter gedreht. Dadurch befindet sich wiederum eine kleinere Bohrung 18 der Drehtrommel 10 im Arbeitskanal 13,11, wodurch die nächste Kernlochbohrung vorgenommen werden kann. Der gesamte Vorgang wird wiederholt, bis alle Schraubenlöcher der Platte mit Knochenschrauben 1 belegt sind.The intraoperative handling of the device according to the invention is described below:
The rotary drum 10 filled with bone screws 1 is pushed into the drum housing 6, 7 without having to handle the individual bone screws 1. The surgeon now uses the device according to the invention initially as a drill sleeve in order to drill the core hole for the bone screws 1 to be placed in the bone. The drill 21 is guided exactly through the drill sleeve 15 of the upper plate 6, through one of the smaller bores 18 of the rotary drum 10 and through the tissue protection sleeve 11. The length of the individual guide elements 15, 11 are matched to the length of the bore. This allows the drilling depth in the bone to be adjusted to the screw length. The tip of the tissue protection sleeve 11 is adapted to the screw holes in the bone plate, as a result of which the bone plate is pressed onto the bone and can therefore no longer slide off. The surgeon now drills the core hole in the bone. After removing the drill 21, the surgeon rotates the rotary drum 10 by an index position 17 by means of its peripheral edge. As a result, one of the ends up in the rotary drum 10 located bone screws 10, in the working channel formed by the elements 13 and 11. Depending on the nature of the bore 4 in which the bone screw 1 is located, the bone screw 1 falls through the tissue protection sleeve 11 onto the bone surface, or it has to be pushed with a screwdriver 22 through the tissue protection sleeve 11 onto the bone surface. The diameter of the screwdriver 22 is adapted to the head diameter of the bone screw 1, so that it is guided over its entire length and necessarily engages in the drive of the bone screw 1 (cross recess, Allen key, etc.). Since the device according to the invention does not have to be removed during the entire working process, the bone screw 1 can be screwed into the bone without looking for the pilot hole.
After the bone screw 1 has been screwed in completely, the screwdriver 22 is removed and the rotary drum 10 is rotated further by an index position 17. As a result, there is again a smaller hole 18 in the rotary drum 10 in the working channel 13, 11, as a result of which the next core hole can be drilled. The entire process is repeated until all screw holes in the plate are covered with bone screws 1.
